SUPPLEMENT TO THE PTC-2234 USER’S GUIDE
INTRODUCTION
This document provides important supplemental information for using the PTC-2234 hand-held
computer. This is a supplement to the user's guide and any other system documentation. In the
event of a conflict between information provided in this document and information in other
documents, this document takes precedence.
The information in this document applies to using PTC-2234 units in hazardous locations and to
using PTC-2234 units with the SRM RFID option.
SAFETY INFORMATION
The Symbol PTC-2234 has been investigated by Underwriters Laboratories for use in Class I,
Division 2, Groups A, B, C, and D Hazardous Locations. On the rear of the PTC-2234 unit under
the battery, the following label indicates that the unit is listed with UL.
TELXON CORPORATION

GROUPS A,B,C, & D
CONNECT ONLY TO LISTED
20BM
SUPPLY, 15VDC, 2.7A
USE ONLY BAT. PACK MODEL 24172-002
If this label is not present, the unit is not approved for use in hazardous locations. The following
instructions apply when using the UL-listed model in Division 2 hazardous locations:
• Do not connect any device or accessory to the PTC-2234 or operate it unless it is specifically
listed for use in hazardous locations Class I, Division 2, Groups A, B, C, and D.
• The PTC’s AC adapter, vehicle adapter, battery charger, and communication cradle are not
listed for use in hazardous locations.
• At this time, no devices are listed for connection to the PTC’s serial/keyboard connector or
for operation from this connector. Do not connect a keyboard or any other device to this
connector unless the area is known to be nonhazardous.
• Do not install or remove PCMCIA cards or the laser scanner module unless the area is known
to be nonhazardous. Once installed, the following devices may be used in hazardous
locations:
• PCMCIA ATA memory cards
• The laser scanner module (part number 19391-103)
• The 2.4-GHz direct-sequence 802.11-compliant spread spectrum radio

SRM RFID OPTION
The SRM RFID system uses Texas Instruments Radio Frequency Identification System (TIRIS)
technology. It emits low-level radio-frequency energy at 134.2 KHz and receives signals from
TIRIS transponders in the same frequency range.
The SRM RFID system works with the PTC-2234 and is fully installed and configured on
delivery. No user installation or tuning is required. Refer to your application software
documentation for details on using the system. The following are general guidelines:
• The radio does not transmit except when initiated by the user. Read operations can be
initiated by pressing the READ button on the SRM RFID handle or through application
software.
• Range is dependent on the relative orientation of the SRM RFID handle and the transponder.
Optimum range is achieved when the edge of the RFID tag is visible through the opening in
the handle. Range is worst when the tag and the handle are in the same plane.
• To achieve optimum performance, sight the RFID tag through the hole in the handle and hold
the computer so that the handle is as close as possible to the tag.
